When does
expanding and simplifying a(b + c) result in
a positive value for ac?
Expanding the expression a(b + c) = ab + ac, the value of ac is positive if both a and c are positive or if both a and c are negative.
Using Basic Distributive PropertiesBy Multiplying the term outside the brackets by each term inside the brackets
Using this method you can distribute the outer terms into the inner terms. You can multiply the term outside the brackets by the first term inside the brackets. Then multiply the outside term by the second term. If there are more than two tribes, then continue to distribute the tribes until the tribe has no remainder. Keep the signs (positive or negative) in parentheses.
For example:
2(x-3) = 10
2(x) – (2)(3) = 10
2x – 6 = 10
We also know that the distribution characteristic state is a(b + c) = ab + ac.
Because plus times plus is plus and minus times minus is plus. When expanding the phrase a(b + c) = ab + ac, the value of ac is positive if both a and c are positive, and the value of ac is negative if both a and c are negative.

The Tour de France is not a 3500 km race, it is a 3500 km cycling race. The diameter of the bike wheels used in the race must be between 55 cm and 75 cm. To find the minimum number of rotations
The minimum number of rotations required for a 3500 km race is 52,800 rotations.
This is calculated by dividing the total distance of the race, 3500 km, by the circumference of the wheel, which is 2πr, where r is the radius of the wheel. The radius of the wheel must be between 27.5 cm (half of 55 cm) and 37.5 cm (half of 75 cm). So, the minimum number of rotations is given by 3500/(23.14r), where r is the minimum radius of the wheel. Substituting in r = 27.5 cm, we get the minimum number of rotations required for a 3500 km race as 52,800.
To arrive at this result, we must first calculate the circumference of the wheel, which is given by 2πr, where r is the radius of the wheel. Since the diameter of the wheel must be between 55 cm and 75 cm, the radius of the wheel must be between 27.5 cm (half of 55 cm) and 37.5 cm (half of 75 cm).
We then divide the total distance of the race, 3500 km, by the circumference of the wheel, which is given by 2πr. Substituting in the minimum radius of the wheel, 27.5 cm, we get the minimum number of rotations required for a 3500 km race as 52,800.

Answer:
D
Step-by-step explanation:
A and B would move the functional graph unchanged 6 units up and down.
but that is clearly not what happened.
so, A and B are out.
h(x) is instead f(x) shifted 6 units to the left.
that means the functional value h(x) is the same as f(x') just 6 units "earlier". that means x = x' - 6 or x' = x + 6.
therefore,
h(x) = f(x + 6) = sqrt(x + 6)

Math-Drills.com
Answer:
Step-by-step explanation:
Sandra, Deacon, and Breanna read a total of 5 + 6 + 7 = 18 books. Since one book was read by all three children, we need to subtract it once from the total. Therefore, they read 18 - 1 = 17 different books.
Sara needed 8 test tubes for 3 different experiments. The first experiment required 2 test tubes, leaving 8 - 2 = 6 test tubes for the other two experiments. Since the two experiments required the same number of test tubes, each one required 6/2 = 3 test tubes.
It is unclear what the question is asking. Please provide more information or a specific question.
Branson and his sister Beatrice combined their allowance of $7 each to buy a movie for $12. They spent a total of 7 x 2 = $14 on the movie. Therefore, they had 14 - 12 = $2 left to buy fruit salad. They bought 2 containers of fruit salad for $1 each, leaving them with $0. They split the containers evenly between them, so each of them got 2/2 = 1 container of fruit salad.
Before Cam broke his right arm, he could type 9 words per minute on his phone. After he broke his arm, he could only type 6 words per minute. The difference between the number of words he could type in 5 minutes before and after he broke his arm is 5 x (9 - 6) = 5 x 3 = 15 words.
Gisselle saved $6 every week for 8 weeks, so she saved a total of 6 x 8 = $48. She found a used bicycle for $50, so she did not have exactly enough for the bicycle. She was $50 - $48 = $2 short.

if you believe bit plane slicing is lossy, can 1st-order extrapolation or 2d bilinear interpolation recover the original image?
If you believe that bit plane slicing is lossy, then 1st-order extrapolation or 2D bilinear interpolation cannot fully recover the original image.
What is extrapolation and interpolation?
Extrapolation is an estimation based on extending a known sequence of data beyond what is absolutely known.
Interpolation is the estimation of a value in a sequence of values between two known values.
Bit plane slicing is a lossy compression technique, which means that some information from the original image is lost during the compression process. The purpose of bit plane slicing is to reduce the size of an image by removing less significant bits from each pixel. As a result, the quality of the image is reduced.
1st-order extrapolation and 2D bilinear interpolation are techniques used to estimate or predict missing or unknown values from a given set of data. These techniques can be used to enhance the quality of an image, but they cannot recover the original image in cases where information has been lost through compression or degradation. In other words, they can only improve the quality of the image to a certain extent, but they cannot restore it to its original state.
So, if you believe that bit plane slicing is lossy, then 1st-order extrapolation or 2D bilinear interpolation cannot fully recover the original image, although they may help to improve its quality to some extent.

3. Mr. Sanchez’s class sold fruit pies for $1.45 each and Mr. Kelly’s class sold bottles of fruit juice for $1.25 each. Together, the classes sold 53 items and earned $70.85 for their school.
(a) Write and solve a system of equations that model the problem. Show all your work.
(b) Which class earned more money?
(c) How much more money did that class earn?
Let x be the number of fruit pies sold by Mr. Sanchez's class, and y be the number of bottles of fruit juice sold by Mr. Kelly's class.
(a) We can set up a system of equations to model the problem:
x + y = 53 (total number of items sold)
1.45x + 1.25y = 70.85 (total amount earned)
To solve this system using substitution, we can rearrange the first equation to solve for one variable in terms of the other:
x + y = 53
x = 53 - y
Then substitute x = 53 - y into the second equation:
1.45x + 1.25y = 70.85
1.45(53 - y) + 1.25y = 70.85
76.85 - 1.45y + 1.25y = 70.85
0.2y = 6
y = 30
Substituting y = 30 into the equation x + y = 53 gives:
x + y = 53
x + 30 = 53
x = 23
So Mr. Sanchez's class sold 23 fruit pies and Mr. Kelly's class sold 30 bottles of fruit juice.
(b) To find out which class earned more money, we can calculate the total amount earned by each class:
Mr. Sanchez's class: 1.45 x 23 = $33.35
Mr. Kelly's class: 1.25 x 30 = $37.50
Mr. Kelly's class earned more money.
(c) The amount by which Mr. Kelly's class earned more than Mr. Sanchez's class is:
$37.50 - $33.35 = $4.15

Find the volume of the solid generated by rotating the region bounded by y = x^2, y = 0, and x = 1, about the y-axis.
Step-by-step explanation:
To find the volume of this solid, we will use the method of cylindrical shells. We will integrate the cross-sectional area of a cylinder, given by πr^2, over the height of the solid. The height of the solid is given by the difference between the upper and lower bounds of the region, which are y = x^2 and y = 0, respectively. The radius of each cylindrical shell is given by the distance of the cross-sectional circle from the y-axis, which is x.
So, the volume of the solid is given by the integral:
V = ∫[0, 1] π * x^2 dx
Using the antiderivative of π * x^2, which is π * x^3 / 3, we can find the definite integral:
V = (π * x^3)/3 from 0 to 1
Evaluating the definite integral and simplifying, we get:
V = π/3 units^3
So, the volume of the solid is π/3 units^3.

a. Each marble has a volume of 0.013 liters.
b. 23.4 liters of water would be necessary if William uses 200 marbles.
a. To determine the volume of each marble, we can use the information that 85 marbles fill a tank with a volume of 20.9 liters of water:
Volume of each marble = (26 liters - 20.9 liters) / 85 marbles = 0.26 liters - 0.247 liters/marble = 0.013 liters/marble
So, each marble has a volume of 0.013 liters.
b. To determine the amount of water necessary if William uses 200 marbles, we can use the formula:
Volume of water = Total volume of tank - Volume of marbles
Volume of water = 26 liters - (200 marbles * 0.013 liters/marble) = 26 liters - 2.6 liters = 23.4 liters

9.5% of Undergraduate students study abroad. 60% of those who study abroad are female. 49 % of those who do not study abroad are female. calculate probability of a female student studying abroad .
The probability that the student is female and studying abroad is equal to 0.057. It means 5.7% of student is female studying abroad.
Given,
Undergraduate students who study abroad = 9.5% = 0.095 undergraduate
female students who travel for study. = 0.60
male undergraduates who travel for study. = 0.40
undergraduate female students who do not study abroad. = 0.49
Those male undergraduates who do not study abroad. = 0.51
Probability refers to potential. It is a field of mathematics that generally examines how the random events happen. The value is expressed as a number between 0 and 1. To determine how likely an event is to occur, probability has been introduced in mathematics.
We know that ,
the probability that the student is female and studying abroad =
0.60 * 0.095 = 0.057

how many different subsets of {1,2,3,4,5,6,7,8,9,10,11,12} contain at least one element in common with each of the sets {2,4,6,8,10,12}, {3,6,9,12}, and {2,3,5,7,11}? (source: mathcounts)
There are a total of 816 different subsets of {1,2,3,4,5,6,7,8,9,10,11,12} contain at least one element in common with each of the given sets
There are 12 elements in the original set, and each of the three smaller sets has different elements. To find the number of subsets that contain at least one element in common with each of the three sets, we need to count the number of subsets that contain at least one element from each set. To do this, we can consider each set separately and multiply the number of subsets that contain at least one element from each set.
The first set has 6 elements, the second set has 4 elements, and the third set has 5 elements. The number of subsets of the first set that contain at least one element is [tex]2^6-1[/tex]=63, the number of subsets of the second set that contain at least one element is [tex]2^4-1[/tex] =15, and the number of subsets of the third set that contain at least one element is [tex]2^5-1[/tex]=31. The number of subsets of the original set that contain at least one element from each of the three sets is 63 * 15 * 31 = 816.
